Humans have been intuitively using speech as the most natural and preferred means of communication. Speech signals are mostly non-stationary processes with multiple components that may vary in time and frequency. Since these signals occur naturally, they are erratic in nature [1]}. Speech signals carry a lot of information and also convey the emotional status of an individual. An emotional speech expresses the patterns of rhythm and intonation, often referred to as prosody in a language [2]}, [3]}.
